To all lwhom t may concern.:

Beit known that I, HARRISON D. MCFAD- DIN, a citizen of the-UnitedStates, residing in East Orange, county of Essex, and State of NewJersey, have inventedl a certain new and useful Lamp-Fixture, of whichthe following is a specification. l

This invention is a lamp fixture, and the object of the invention is tosupport a lamp and shade in a particularly simple, attrac-` tive ande'ective manner.

The invention will be described particu-v larly in connection with itsapplication as an electric light fixture, although it will be apparentthat certain advantages may be availed of in lamps of other types.

In lamp shades or reflectors for electric lights, as heretoforeconstructed, it has been customary to form an imperforate reector orshade and to subsequentlyv drill holes orV cut openings therein, usually`in opposing relation, to permit of its being rotatably mounted on thetrunnions forming a part of the lamp xture. 'lhe operation of drillingthe holes is not only expensive, but results in a considerable loss frombreakage and, further, weakens the resulting structure.

The present invention, in contradistinction to those 4prior art deviceswherein the shade' is supported on trunnions passing through aperturesin the shade, is supported preferably fromyits lower edge and in suchmanner that a pivotal support is secured without necessitating theemployment of trunnions.

The present invention, moreover, permits of the sliades being detachedand a new one replaced without necessitating the removal of the lampsocketor interfering with the' wiring, said wiring being preferablyinvisibly incased within the shadesupporting bracketD A further featureof the invention resides in the fact that the clamps by which thereflector is secured to the bracket are positioned interiorly of thereflector, whereby, when the reflector becomes heated, the expansionthereof is Vin a direction away from,

the clamps, thereby reducing the pressure on the clamps with consequentless danger of breakage of the glass from which said relectors areusually made.

The absence of trunnions in the lamp X- ture of the present invention,as well as thev fact that the clamping devices are relatively small andpositioned near the lower edge of the reflector, result incomparativefreedom bers on the bracket coperate to fixedly secure thereector in position.

Features of the invention, other; than those specified, willibe apparentfrom the hereinafter detailed description taken in conjunction with theaccompanying drawings. l

In the accompanying drawings, l have illustrated one practicalembodiment of the invention, but the construction shown therein is to beunderstood as illustrative, only, and not as defining the limits of theinvention.

Figure 1 is a side elevation of a lamp bracket embodying the presentinvention. Fig. 2 is an underneath plan view of the same. Fig. 3 is atop plan view of the fixture with the shade or reflector detached. Fig.4 is a front elevation of Fig. 3. Fig. 5 is a section taken on line 5 5of Fig.l 4, showing the manner in which the reflector or shade isretained within the fixture. Fig. 6 is a perspective detail of one of aplurality offclamping means whichl employ, and Fig. 7 is a transversesection4 of the preferred form of reflector.

Referring to the drawings, the shade or reflector supporting member isdenoted by the reference numeral A. rlhis supporting member is mountedby means of any suitable pivotal connection B on a wall bracket,portable standard, or the like. Supporting member A is channeled incross-'section throughout its entire extent, so as to be adapted toreceive the lower edge of a shade. lt is, therefore, in shape.substantially that of the contour f the shade, or that portion thereofwith which it is adapted to coperate. As shown in Figs. 1 and 2, lpreferably proportion supporting member A. so as to embracesubstantially one-half of the lower edge of the shade. Thus, when ashade C is placed on the fixture with a portion of its lower edgepositioned within the channel lof supporting'member A, the weight ofsaid shade will be distributed throughout the entire extent of thesupporting member, and the strain onsaid supporting member willbe'minimized.

In order that convenient means may be provided for maintaining the shadeagainst 'inadvertent displacement from its supporting member and toproperly support the weight of the shade on said member, said shade ispreferably provided with a hooded lateral extension c, which, when theshade is in place, is housed within the channel of member A. Member A,to increase its esthetic appearance and strength, is preferably taperedin depth from the plug a, which forms its support, to the free endsthereof, and the channel interiorly of said member is, therefore,likewise tapered in depth. The offsetting of shade C, as at c, provideson the Aexterior of the shade a shoulder c', adapted to rest upon theupper edge of supporting member A, at the outer side of the channelthereof, and'form 'a seat for the shade upon said supporting member.Moreover, the oflf ,setting of portion c of the shade forms a shoulderc2 interiorly thereof, which I utilize in locking the shade againstinadvertent displacement from the channel of supporting member A.

Positioned within the channel of supportin'g member A, in recesses d, isa plurality of clamping members D, one of which is shownI in perspectivein Fig. 6. These clamping members are pivoted, at d, to the interiorwall of the supporting member, and, at the opposite ends of the clampingmembers from their points of pivoting, are laterally extending flangesd2, adapted, when the clamping members are folded down into the recesses(Z, to engage with shoulder c2 of shade C. Each clamping member D isprovided with a lug e, projecting laterally in an opposite directionfrom -flange d2, which lug is adapted to overlie the interior edge ofsupporting member A. Each lug e is provided with a threaded tap e', intowhich is adapted to be screwed a bolt e2 mounted on'a bracket e3 on theinterior of supporting member A. A collar e4 is fixed on each of saidbolts to preclude their longitudinal movement.

It will be manifest, from the foregoing description of the clampingmeans, that each clamping member is pivotal about its point ofattachment d', and maybe either folded into the recessescl of supportingmember A into its closed position, or swung upwardly into the vertical,open osition illustratedby clamping member in Fig. 4. When it is desiredto positionv a shade upon supportin member A, all of the clampingmembers are swung to their open posltion the clamping members tightlyinto engagement with shoulder c2 of the lamp shade, and lock the same inthe channel against inadvertent displacement.

The lamp socket F, which is adapted to receive the threaded plug of anelectric lamp -or bulb F', is preferably supported upon the fixture byvirtue of the gripping action of a split ring f, which is fixed to theinterior of supporting member A and may be regulated by screw f to gripor release socket F. In initially assembling the bracket, split ring fis formed integral with, or is xedly attached to, supporting member A,the base of socket F inserted thereinto, and screw f tightened to causering 7 to ti htly grip said socket. It will be noted, in ig. 3, that thesocket and clamping means are positioned ltinteriorly of the channelwhereby a shade may be removed from the xture and another `replaced,without necessitating the removal, or any manipulation whatever, of

the lamp socket or lamp F, supported therein. The current for operatingthe lamp is fed through wires g g', which are led through the pivotalconnection B and threaded plug'a into the channel of the supportingmember, thence through said channel, below the edge ofthe lamp shadesupported therein, to lamp socket F, as clearly shown in Figs. l, 2 and3. It will be noted, from Fig. 5, that the supporting of lamp shade Cupon shoulder c precludes said lamp shade from projecting to the bottomof the channel and thereby leaves a space along the bottom thereof,which forms a conduit for the wires g g', and said wires are, therefore,entirely obscured from view.

It will be manifest, from the foregoing description, that thepositioning of the shade clamping devices interiorly -of the supportingmember, as well as the passing of the wires through a closed conduit,renders the fixture entirely free from all unsightly projections, andmaterially increases itsesthetic appearance. Moreover, the fixtureconforms to the contour, and, in every way, follows the general lines,of the shade,

use, and the inherent .objection of shadows in these devices isobviated. It will further appear that, since the clamping members arepositioned interiorly of the shade, the expansion of said shade, whenheated, will cause the portions of said shade held by said clamps torecede, rather than to bind, at the clamping points. 'This obviates alltendency to breakage under expansion, an objection inherent ,inpractically all of the lamps now on'the market. The positioning of thelamp socket interiorly ofthe shade andthe supporting thereof entirelywithin the inner contour of said shade, and the leading of thecurrent-supplying wires through the channel 'of thev supporting memberbeneath the' edge of said shade, obviate the necessity, inherent inprior devices, of removing or dismantling a portion of the lightingsystem or wiring, when removing or replacing a lampA shade on thebracket. A further 'feature of advantage .resides in the improved mannerof fiXedly mounting the lamp bracket on the fixture, by means of thesplit ring shown. By this method, the base of the lamp socket ispractically in Contact with the interior of the shade or, in otherwords, is positioned closer to the end of the shade than has heretoforebeen possible.

accompanying drawings, I have illustrated the preferred practicalembodiment of my invention. It willibe understood that I do not-restrictmyself to the specific details of construction therein described andillustrated-c. g., there are many clamping means which may be utilizedin securing the shade in position within the channel of the supportingmember and I do, therefore, wish it understood that I consider myinvention as 'broadly novel as commensurate with the appended claims.

Having thus fully. described the invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a lamp bracket, a channeled supporting member adapted to conformto, and house, the lower edge of a reflector, the channel of thesupporting member being of such depth as to leave a conduit intermediatethe edge of the reflector and the base of the channel, a lamp socketmountedon the supporting member, and electric w1res passing through theconduit intermediate the bottom of the channel and the edge of thereflector and in communication with the lamp socket,

. whereby said wires are concealed from view.
